features:
  - |
    Move base_client from tempest.lib.services.volume.v3 to
    tempest.lib.services.volume, so if we want to add new
    interfaces based on a v2 client, we can make that v2
    client inherit from volume.base_client.BaseClient to
    get microversion support, and then to make the new v3
    client inherit from the v2 client, thus to avoid the
    multiple inheritance.
deprecations:
  - |
    Deprecate class BaseClient from volume.v3.base_client
    and move it to volume.base_client.
    ``tempest.lib.services.volume.v3.base_client.BaseClient``
    (new ``tempest.lib.services.volume.base_client.BaseClient``)
